Flowing mixer - fix the problem
Cartridge or ball single-lever mixers are quite popular today. They are convenient to use, and are considered the most modern execution of valves. Over time, however, they can flow. What is the reason for such a failure and how to eliminate it? Such a phenomenon, unfortunately, is not uncommon. Since the taps are the final devices in the wiring diagram, the water pressure drops have a detrimental effect on their moving part. In ball valves and mixers most often suffer cartridges that are responsible for the preparation of water of the desired temperature. How to replace them correctly, without damaging the mixer, we will tell you now.
Ball cartridge cartridge deviceThe cartridge is a small plastic cylinder with a square cross section sticking upwards. The rotary mechanism of the cartridge changes the position of two adjacent ceramic plates or discs. They are polished and lubricated with silicone grease.Each of them has three holes - for cold, hot water and a tap outlet. Their combination and gives a certain proportion and pressure of water. At the exit from the holes of the discs, seals are fixed, which are responsible for sealing the cartridge in relation to the body of the crane. /posts/2018-04/medium/1523358392_kartridzh_dlya_smesitelya_40_mm.jpg "style =" max-width: 100%; " alt="Mixer cartridge">
What you need to work
- New cartridge;
- Adjustable wrench;
- Knife or screwdriver;
- 2.5 mm hex (for the presser foot bolt).
Changing the cartridge in the mixerBefore starting any work related to the repair or replacement of valves, it is necessary to shut off the water supply in the line so as not to make a flood. For the majority of intra-house and apartment wiring, the first ball valve in the assembly with a water meter located on the riser or main pipe is responsible for this. To get to the cartridge, you need to disassemble the inside of the mixer. We begin to do this by dismantling the rotary switch or tap foot. On its body there is a small cap with the designation of the type of water: blue - cold, red - hot.We hook it with a sharp tool - a knife or a screwdriver - and unscrew the clamping bolt with a hexagon on the stem bushing.
Practical tipsThe quality of the water, its hardness and the presence of hard impurities - debris, sand, rust, etc - affect the wear of the cartridges. d. Due to friction, they wear plates and seals, which can lead to leakage or "squeezing" in the system when hot water displaces cold water through the formed gaps in the mixer. Experienced masters advise to include in the wiring diagram a cleaning filter, having ascertained the composition of water and impurities in it. Also pay attention to the quality of purchased faucets and mixers.Savings in this case may cost to repair not only the cartridge, but also the room, and not only your own.
